Cephalosporin Cephalosporin review
Pharmacy and Drugs

     .: Prescription

Cephalexin is an antibiotic in a class of drugs called cephalosporins that works by fighting bacteria in the body. This medicine is used to treat many different types of bacterial infections such as respiratory tract infections (bronchitis, tonsillitis, ear infections (otitis), pharyngitis); skin infections and urinary tract infections (UTIs). This is also used for the treatment of gonorrhea and syphilis which are sexually transmitted infections when penicillin is unsuitable.

Special precautions: kidney disease or a gastrointestinal disease such as colitis; individuals with diabetes may need to be aware of the sucrose contained in cephalexin suspensions; pregnancy and lactation. Cephalexin is in the FDA pregnancy category B which means that it is not expected to be harmful to an unborn baby. This medicine also passes into breast milk and may affect a nursing infant. Do not take this medication without first talking to your doctor if you are pregnant, could become pregnancy during treatment or if breast-feeding a baby.

Do not take cephalexin if you have ever had an allergic reaction to another cephalosporin or to a penicillin unless your doctor is aware of the allergy and monitors your therapy. Take all of the cephalexin that has been prescribed for you even if you begin to feel better. Your symptoms may start to improve before the infection is completely treated. Cephalexin can be taken on an empty stomach or with food or milk if it causes stomach upset. There are no restrictions on food, beverages, or activities during treatment with cephalexin unless otherwise directed by your doctor.

Symptoms of a cephalexin overdose may include nausea, vomiting, diarrhea, abdominal cramps, seizures, numbness and tingling in the arms or legs, and muscle spasms. Seek emergency medical attention if an overdose is suspected. Serious side effects: an allergic reaction (difficulty of breathing; closing of the throat; swelling of the lips, face, tongue; hives; or a rash); redness or itching; severe nausea, vomiting or diarrhea; mucous or blood in the stool; unusual bleeding or bruising. Other less serious side effects are: mild nausea or diarrhea or a yeast infection of the mouth or vagina. Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.

Drug interactions: probenecid (Benemid); a loop diuretic (water pill) such as furosemide (Lasix) , bumetanide (Bumex); torsemide (Demadex), or ethacrynic acid (Edecrin); warfarin (Coumadin); or another antibiotic. You may require a dosage adjustment or special monitoring during treatment if you are taking any of the medicines listed above. Drugs other than those listed here may also interact with cephalexin. Talk to your doctor and pharmacist before taking any prescription or over-the-counter medicines, including vitamins, minerals, and herbal products.
